Sometimes multiple pieces of information, none of which alone is considered PII, might still uniquely identify a person when combined. For example, what if a company employ only one 39-year old female with a residence in Roanoke, Virginia. In that case, the employer, age, gender, and city of residence are not PII elements by themselves, but become PII when they are presented together. This scenario is an example of PII established through indirect inference, while data elements such as a driver's license number constitute PII through direct inference.
